Be it known that I, HERMAN P. PORTER, a citizen of the United States, residing at Jacksonville, in the county of Duval and State of Florida, have invented certain new and useful Improvements in Sash-Locks, of which the following is a specification.

This invention relates to certain novel, new and useful improvements in sash-locks especially designed to securely lock the meeting rails of sashes together to prevent unauthorized manipulation of either sash, and at the same time serving as an antirattler. i v r The prime object of the invention is to provide simple, durable, economical and efficient means for tightly and securely locking the meeting rails of sashes in contact with each other, consisting of a spring pressed bolt carried by the top rail of the lower sash, adapted to engage witha spe-v cial. type of keeper seated within a suitable recess formed inthe adjacent edge of'the lower rail of the upper sash and rigidly .secured thereto. r Further objects of this invention are so to construct my novel locking means that the locking 5 bolt will enter the locking keeper whether it is placed straight orin a slanting position; that when the bolt is unfastened the spring will project it sufii cie'ntly inward to clear its outer end from contactwith the meeting rail of the upper sash'thereby avoiding the scarring or scraping of the wood as the lower sash is'moved up and down, and so that the ti hter-the lock bolt is screwed inward the closer and more effective will be the joint of the con tact faces of the meeting rails, whichpermits the locking means to .also serve t e purpose of an antirattlen. r

' The foregoing and such other objects as may appear from theensuing-description are attained by the novel features of construction, arrangement, combination and location of parts hereinafter more fully described, illustrated in the accompanying struction may be resorted to without departe v drawings, and particularly pointed-out in the claimsappended hereto, it beingunderstood that slight changes in the precise form, proportions and minor details of the conthe several views, it will be seen that F igure 1, 1s a transverse sectional view through the meeting rails'of the two sashes showing the means embodying my invention 1n its locked position;

Fig. 2, is a similar view showing the looking, bolt in its unlocked, or inwardly proected position. H I 3 Flg. ,3, is an elevation'of the looking keeper carried by thelower rail ofthe upper sash and removed therefrom. Y

Fig. 4, is a longitudinal section taken on the line l'4, Fig. 3.

Fig.5, is a detail plan viewof the was her whlch engages the locking bolt.

Fig; 6, is a detail longitudinal section of the slotted washer or casing'secured atlthe inner end portion of the bolt, and 1 Fig. 7, is a detail side elevation. of the inner casing or housing carried by the upper sash rail of the lowersash. In carrying out my invention as illustrated, and ,which shows a., preferred con struction,the numeral 1 designates the upper rail of the lowersash and 2 the lower rail of the upper sash with their meeting faces in contact with each other as shown in Figs. 1 and 2. WVithin thevupper rail of the lower.sash is bored two sizes of holes or openings .andsuitably secured within the larger hole vis a tubular casing or housing 3, and within the smaller hole is secured a slotted washer or smaller mange, said cas-,

ings surrounding". the major portion of a locking bolt .5, provided with a screw threaded inner end; portion'6, an integral shouldered portion 7 formed intermediate its length and an inner handle member 8',

said bolt mechanism being securely fastened 7 to the upper rail ,of the lower sash by means of a metallic plate 9, rigidly and securely fastened in any suitablemannerto theinner face of said upper rail, Embracing the bolt 5 and resting in contact with the shouldered portion thereof is a slotted washer 1,0, and

surrounding that portion of the bolt within said upper rail with its inner end portion in contact with the outer face of said washer 10 and its outer end in contact with the inner face of the slotted washer or casing 4, is a coiled spring 11 for the purpose hereinafter described. Rigidly secured within a suitable recess formed in theouter face of the upper rail is a metallic plate 12' formed with a central opening for the passage of the locking bolt therethrouglnthe outer end of the slotted washer or casing 4 resting in contact with the inner face of said plate 12. Permanently and rigidly secured in a vertical position within a suitable recess formed in the inner face bf the lower rail ofthe top sash is a metallic keeper plate 13, with a central opening 14: formed therethrough, the opposite side edges of said opening having an inner inclined integral extension 15, and an outer inclined integral extension 16 forming a part of said plate 13, as shown in Figs. 8 and 4, said extensions projecting slightly above the central portion of said opening 14, and adapted to engage with the inner threaded end of the locking bolt whether it is placed straight or in an inclined position, and the farther the bolt is screwed within the keeper, with its inner end projecting into the recess 16 formed in said lower rail, the tighter and closer the joint is made between the meeting rails of the sashes, the said locking means thereby also serving as an antirattler.

In assembling the parts of my novel looking means all of said parts being preferably made of brassor other non-corrosive material, the slotted washer or casing 4; is first seated within the smaller bore with its outer end in contact with the inner face of the plate 12 and its elastic side wall in contact with the wall of the bore, then the casing or housing 3 is placed within the larger bore with its outer edge resting on the shouldered portion 17 formed by said larger bore,- the locking bolt is passed through the metallic plate 9, the slotted washer 10 is then seated against the shouldered portion 7 formed on the bolt, after which the coiled spring is placed in its proper position surrounding a,

portion of the bolt; the bolt inserted within the opening formed in the upper sash, and the locking mechanism secured thereto by the plate 9 fixedly fastened to the inner face of said upper rail; 7

It will be readily perceived that when the locking bolt is released from its locking keeper 13, the coiled spring will immediately be expanded and project the bolt inward to the position shown in Fig. 2, with its inner end within the outerface of the top rail of the lower sash, thereby avoiding any tendency to sear or scratch the inner face of the lower rail of the upper sash,as the lower sash is moved upon or down.

It will be seenthat my novel locking casing fitted within the larger opening, a

means can only be used by boring two sizes of holes within the upper rail of the lower sash for the reception of said means for the purposes hereinbefore referred to.

Having thus described my invention, what I claim anddesire to secure by Letters Patent is 1. The combination with meeting sashrails, one of said sash rails having two sizes of openings formed therein, of a tubular casing fitted within the larger opening, a slotted casing fitted within the smaller opening, a locking bolt revolubly mounted in said 7 openings, a slotted washer embracing said bolt, and a spring surrounding the bolt with one end in contact with thewasher and its other end in contact with said slotted casing.

2. The combination with meeting sashrails, one of said sash rails having two sizes of openings formed therein, of a tubular slotted casing fitted within the smaller opening, a locking bolt revolubly mounted within the said casings and provided with a shouldered portion, a slotted washer embracing said bolt in contact'with its shouldered portion, a plate fixedly secured within a recess formed in the rail, and a coiled spring surrounding a portion of the bolt with one end resting in contact with said slotted washer and its other end in contact with the inner end of the slotted casing.

3. A sash lock of the character described, comprising a tubular casing fitted within an opening formed in one of the sash rails, a smaller slotted casing fitted into a smaller opening formed in the sash rail, a locking bolt revolubly mounted within said casings having a shouldered portion formed thereon, a slotted washer embracing said bolt in contact with its shouldered portion, a spring surrounding a portion of the bolt with one end resting in contact with said washer and its other end in contact with the inner end of the slotted casing and means for securing said mechanism within the said openings. 7

4;. Aisash lock of the character described, comprising. a tubular casing fitted in an opening formed in one of the sash rails, a smaller slotted casing fitted into a smaller 115 opening in said rail, a locking bolt revolubly mounted within said casings having an outer diate shouldered portion, a slotted washer embracing said bolt in contact with its shoul- V I dered portion, a coiled spring surrounding a portion of thebolt with one end resting in contact with said slotted washer and "its other end in contact with the slotted casing, and a keeper secured to the other sashrail provided with an opening formed therethrough with an inclined extension formed" on either side thereof adapted to engage with the threaded end of the bolt for securing the sash rails together. V

5. A sash lock of the character described, comprising a spring locking bolt revolubly mounted in the upper rail of the lower sash provided with a screw-threaded inner end portion, and a keeper fixedly secured to the lower rail of the upper sash, said keeper being formed with an inclined integral extension formed at opposite sides of the walls of a central opening through said keeper with one extension projecting inward and the other extension projecting outward, both extensions projecting above the central portion of said opening and adapted to engage the screw-threaded end of the locking bolt when i in either a straight or. inclined position;-
